This oil pump is manufactured with standardized specifications, delivering reliable performance for excavator operation in construction and mining sites. It is built with high-strength alloy materials, offering excellent structural durability and heat resistance to adapt to long-term high-load working environments. The precision-machined internal structure ensures stable oil flow transmission, maintaining flow integrity during operation and effectively avoiding insufficient lubrication caused by external debris intrusion. It matches the installation dimensions of factory standard parts, requiring no modification during assembly, which reduces maintenance downtime. The product undergoes strict pressure and sealing tests before leaving the factory, ensuring consistent performance matching the working requirements of heavy excavator engine systems.
